A tamper resistant electrical receptacle is disclosed that includes a cover having two cover apertures, a platform, a slider positioned between the cover and the platform and coupled to the platform, and a coil spring. The platform includes two platform apertures aligned with the two cover apertures, a channel between the two platform apertures, and a pin trap channel separate from the two platform apertures for trapping a pin inserted into one of the two cover apertures. The slider includes a post that engages the channel, and shutters connected to the post. The coil spring is coupled to the slider and has a resting state in which the shutters are interposed between the cover and platform apertures, and a compressed state in which the shutters are not interposed. The slider glides along the channel of the platform as the coil spring moves between the resting and compressed states.
